HAND-STAMP.

To all whom z't may concern Be it known that 1,4MAns1IALL TILDEN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Hand- Stainps; and I do hereby declare the; following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to malte and use the same.

This inventionrelatesto improvements in hand stamps and more particularly to egg stamps and has for its object to provide a stamp which will be so constructed and arranged that a name or other desired inscription may be printed upon an egg, thereby disclosing the name or identity of the egg and date of its production; thus preventing deception in the sale of inferior eggs to the consumer.

A further object of my invention is to provide astamp for use not only-on convex suaces but on concave and fiat surfaces vas W Brieflystated this .invention is a combination stamp telescopic in construction, or a stamp within a stamp, removably secured or locked one wit-hin the other and operated by tl1e=handle of the inner stamp the same way as viscustomary with any ordinary stamp.

Other objects and advantages will be apparent from the following description and more particularly .pointed out inthe claims.

kIn thedrawings Figures l and 2 are side elevations of the invention. Figs. 3 `and 4 are side elevations partly in section. `Fig.5 is a bottom plan. Fig. 6 -is a side elevation partly in section of the outer stamp. Fig. 7 is a side elevationfof theinner stamp. Fig. 8 is a sectional view of a convex-disk. Fig. 9 is a top plan and sectional elevation of a modiiied form of the rubber diaphragm. Fig. '10 is a'top plan and an vedge view of diaphragm. Fig. 11 is a perspective -v'iew of type. Fig. l2 is a perspective view of a' rubber cushion type-holder.

Referring to the drawings, 1 represents the inner stamp which also serves as a handle for the proper manipulation of both the inner and the outer stamp which, combined, form the stamp.

2 represents the outer stamp which is removably secured to the inner stamp by the screw 3 through slot 4. The type 5 is Se- Bpeoioation of Lettersfatent.

cured to diaphragm 6 which is drawn *over the lower .end pf the outer stamp 2 and secured by band 7 as shown in Figs. 1 and 2.

'(lhe spring 8 encircles the lnner stamp its endsengaging shoulders on-the inner .an .outer stamp, as shown in Figs. 3 and 4. The spring is of such strength that the impression of the outer stamp is vmade before the type of the inner stamp reaches the surface to be printed as the force of the spring must be overcome before the inner stamp can t reach said surface; thus obviating the making of a blurred impression. It is possible to operate the stamp Without the use of the spring but its use is preferred.

9 is a .mortised rubber cushion or type holder secured to the bottom of the inner stamp, as shown in Figs. 3 and 4.

10 is a perforated type for use in typeholder. The perforation renders the type more flexible and allows it to conform to the surface to be printed. Ordinary type may be .used if desired.

In adjusting the rubber diaphragm 6 to the outer stamp 2, it is placed over the grooved end 1l as shown in Fig. 6, with the opening directly over the center. The metal band 7 is then placed over the end of the rubber diaphragm pressing its edges over the groove. Said edges are then trimmed so that when the band is pressed farther into position the ruflied `edges of the rubber fall into the groove, thus fastening the diaphragm securely. The diaphragm is formed of thin rubber, consequently it is very flexible and yielding and in conjunction with the mortsed rubber cushion onthe inner stamp will conform to any surface either fiat, con- Vex orl concave.

It will be -seen and understood that, in Operation, the telescopic construction, or the sliding of one stamp within the other, which is ncontrolled by the spring, allows the type atftheend ofeach stamp to meet the inking -surface of an ordinary -inking pad for inlring purposes when applied in the manner usual with hand stamps. the pad the spring forces the stamps to take the position shown in Figs. 2 and 3 and it is then ready to make an impression upon an egg or other surface, as shown in Fig. 4. l

Y By the same operation as above described an impression may be made upon a flatsurface, but preferably the outer stamp should be lockedto the inner stamp, as shown in When removed from f -and a rubber type-bearin Fi l, thus preventing the telescopic act-ion and` forming an ordinary hand stamp. For

rinting on concave surfaces the end of the inner stamp Fig. 7 ma be made convex or the disk, fiat on one si e and convex on the other, as shown in Fig. 8, may be inserted between the rubber cushion and the end of said inner stamp and accomplish the same purpose. Preferably 4the same result may be obtained with no readjustment of the stamp, as stated above. The construction of this stamp is such that, at the will of the operator, he may make an impression with both inner and outer stamp or with the outer f stamp only. Thus if it is not desired to date certain eggs the date-may be omitted without removing the dating type b simply3 holding the outer stamp between t e thum and iinger when operating it.

What is claimed is 1. A hand stamp telescopic in construction, comprsin a stam -within a stamp inovably secure one within the other; a rubber cushion secured to the lower end of the inner stamp and a rubber diaphragm having a central opening secured to the lowerend of the outer stamp said hand stamp automatically adjusting itself for inking and printing purposes as shown and described.

2. A hand stamp telescopic in construction comprising a stamp within a stamp, movably secured one within the other; a type-bearing mortised rubber cushion secured to the lower end of the inner stamp and a typebearing rubber diaphragm having a central opening secured to the lower end of the outer stamp: said hand stamp automatically adjusting itself for inking purposes and for printing upon either convex, concave or fiat surfaces.

3. A hand stamp telescopic in construction comprising an inner and an outer typebearing portion, movably secured one within the other; a mortised rubber cushion secured to the lower end of the inner portion diaphragm secured to the lower end of t e outer portion: said stamp automatically adjusting itself for inking and printing purposes.

4. A combination hand stamp telescopic in construction, comprising two type bearother, a rubber cus ion secured to the end of the inner portion and a rubber diaing portions one artially enveloping the phragm secured to the lower end of the outer portion, a screw 3 movably securing said portions and an adjusting spring 8 encircling the inner ,type-bearing portion, the ends of said spring engagin both said portions: said stamp being a apted to print either with the outer portion or with both combined without readjustment.

5. A combination hand stamp telescopic in construction, comprising two type bearing portions movably secured one within the other, the inner of said portions being provided with a mortised rubber cushion; the outer portion having a typebearing rubber diaphragm with a central opening, secured to its base.

6. A hand stamp comprising a tubular base member having a perforated elastic type-bearin diaphragm secured to the lower end thereo an inner member having an elastic cushion mounted upon the lowerend thereof slidably mounted 1n said base member, said cushion having an opening therein ada ted to be brought into register with the perfbration in the diaphragm; means to retain said members in their operative position; and means to immovably lock said members together when desired.

7. A hand stamp comprising a tubular base member having a rubber diaphragm secured to the lower end thereof; an inner member having a rubber cushion mounted upon the lower end thereof slidably mounted in said base member, said cushion being adapted to bear upon the inner surface of said diaphragm when in an operative posi tion; means to retain said members in their operative position; and rubber typ-e adapted to said members for inking and printing purposes, all substantially as shown, described and for the purposes set forth.

In testimony whereof l aiiix my signature, in presence of two witnesses.
